EOQ, Safety Stock, Lead Time, Batch Size, and JIT Bateman Company produces helmets for drivers of motorcycles. Helmets are produced in batches according to model and size. Although the setup and production time vary for each model, the smallest lead time is six days. The most popular model, Model HA2, takes two days for setup, and the production rate is 1,275 units per day. The expected annual demand for the model is 61,200 units. Demand for the model, however, can reach 76,500 units. The cost of carrying one HA2 helmet is $3 per unit. The setup cost is $10,200. Bateman chooses its batch size based on the economic order quantity criterion. Expected annual demand is used to compute the EOQ. Recently, Bateman has encountered some stiff competition-especially from foreign sources. Some of the foreign competitors have been able to produce and deliver the hets to retailers in half the time it takes Bateman to produce. For example, a large retailer recently requested a delivery of 20,400 Model HA2 helmets with the stipulation that the helmets be delivered within seven working days. Bateman had 5,100 units of HA2 in stock. Bateman informed the potential customer that it could deliver 5,100 units immediately and the other 15,300 units in about 14 working days-with the possibility of interim partial orders being delivered. The customer declined the offer indicating that the total he delivered within seven working days so that its stores could take advantage of some special local conditions. The customer expressed regret and indicated that it would accept the order from another competitor who could satisfy the time requirements. Required: 1. Calculate the optimal batch size for Model HA2 using the EOQ model. Round your answer to the nearest whole number if rounding is required. X units Was Bateman's response to the customer right? Would it take the time indicated to produce the number of units wanted by the customer? 2. Upon learning of the lost order, the marketing manager grumbled about Bateman's inventory policy, "We lost the order because we didn't have sufficient inventory. We need t carry more units in inventory to deal with unexpected orders like these." Do you agree or disagree? How much additional inventory would have been needed to meet the customer's requirements? X additional units If it is common for the excess demand to occur from just a few very large orders during the year, will Bateman need to carry more inventory in order to meet the demand? 3. Fenton Gray, the head of industrial engineering, reacted differently to the lost order: "Our problem is more complex than insufficient inventory. I know that our foreign competitors carry much less inventory than we do. What we need to do is decrease the lead time. I have been studying this problem, and my staff has found a way to reduce setup time for Model HA2 from two days to 1.5 hours. Using this new procedure, setup cost can be reduced to about $94. Also, by rearranging the plant layout for this product-creating what are called manufacturing cells-we can increase the production rate from 1,275 units per day to about 3,400 units per day. This is done simply by eliminating a lot of time and waiting time-both non-value-added activities." Assume that there are eight hours available in each workday. Assume that the engineer's estimates are on target. Compute the new optimal batch size (using the EOQ formula). Round your answer to the nearest whole number. units What is the new lead time? Round your answer to one decimal place. hours Given this new information, would Bateman have been able to meet the customer's time requirements? 4. Suppose that the setup time and cost are reduced to 0.5 hour and $10, respectively. What is the batch size now? Round your answer to the nearest whole number. units
